This is a blog about marketing, gadgets, travel, privacy and cyberspace. Especially, but not exclusively, for those with an interest in everything that can make the life of a frequent traveller into something vaguely resembling normalcy.

This is a signal that should be picked up by everybody who considers building tracking techniques into their service model. People are becoming increasingly conscious of their privacy, and it doesn't help if tracking their behaviour becomes more intrusive than strictly necessary.

You don't need to tag everything and everybody in order to optimize your business: you can often use other techniques, such as QR codes or Colorzip icons.

There's a simple rule of thumb here: objects don't act, so these need to be tagged; they also don't need privacy. People can act on their own, so you want their cooperation. Make them react to your offers or instructions of their own free will; that way you create committed customers and you don't unnecessarily invade people's privacy.
